The reason I choose to do punnett squares was because it can show the probability of diseases or appearance, etc. in your children. I thought this was cool because if they already have ways to predict the outcome of certain genes in our children, than it makes me wonder what will be discovered in the future. Punnett squares are also very easy to follow because it is almost like a little game. They represent two things called phenotype and genotype. When you create punnett squares you always have a capital letter represent the dominant allele and a lower case letter represent the recessive allele. On the top of the square you write one gene pair, and on the left side you write the partner's gene pair.
After reading an article on a website I remembered that when a dominant and a recessive allele are resulted together the dominant always shows over the recessive. Therefore, if B represents brown eyes and b represents blue eyes and they combine then the offspring would have brown eyes. As I read further I saw it was talking about how if a gene in an offspring becomes dominant, the recessive allele is still carried within that offspring.
